Technical Field

The invention relates to an automobile production process, in particular to automatic film sticking equipment and a film sticking method thereof.

Background

Because automobile body part can not put into use at once after the completion of making, place easy deposit dust or by the fish tail for a long time, for example car highlight B post, surface smoothness is higher, is easily by the fish tail, in the car course of working, need carry out the pad pasting to the surface of product, and current sticking film machine degree of automation is low, and its step of drawing the membrane, cutting the membrane, pad pasting needs to be assisted with manual operation through different equipment and accomplishes.

For example, an "automatic laminator for automobile wheel rims" disclosed in chinese patent literature, which is disclosed as CN201620334263.0 and includes a mold-taking and conveying mechanism, a film-laminating mechanism, and a bottom film-separating mechanism, has disadvantages that the laminating film of the apparatus needs to be cut into a desired size in advance and manually placed on the apparatus for alignment, the amount of manual operation is large, and integration of film-drawing, film-cutting, film-pressing, and film-laminating cannot be achieved, resulting in low laminating efficiency.

Disclosure of Invention

The invention aims to solve the problems that in the prior art, the integration of film drawing, film cutting, film pressing and film pasting cannot be realized, the manual operation amount is large, and the automation degree is low when a film is pasted on an automobile part, and provides automatic film pasting equipment which can realize the integration of film drawing, film cutting, film pressing and film pasting, and is small in manual operation amount and high in automation degree.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention discloses automatic film sticking equipment which comprises a base, a film sticking clamp and a film sticking material roll, wherein a product explorator for positioning a product is installed on the base, a film pressing component for pressing a film, which is pulled out from the film sticking material roll, on the product is arranged on the film sticking clamp, a first film cutting component for cutting the film from the film sticking material roll is also arranged on the film sticking clamp, a film pulling component for pulling the film out from the film sticking material roll again after cutting is also arranged on the film sticking clamp, and the movement of the film sticking clamp is controlled by a robot.

The product leans on the fixed product of membrane, prevents to receive frictional force and remove at the pad pasting in-process product, draw the membrane subassembly and pull out the pad pasting through horizontal migration and the level is arranged in press mold subassembly downside in rolling up the pad pasting from the pad pasting, the press mold subassembly presses the surface of product through the downstream, pad pasting anchor clamps are through removing the pad pasting completely on the product at the product surface, first cut out the membrane subassembly and roll up from the pad pasting and cut out through the downstream with the pad pasting that pastes on the product.

Preferably, the base is provided with a second film cutting assembly capable of moving in the horizontal direction, and the film sticking clamp is provided with a traction rod capable of driving the second film cutting assembly to move; the membrane subassembly is cut out through horizontal migration on the base to the second can lie in first cut out membrane subassembly different orientation and cut out to, when the limit that needs to cut out is longer, can reduce the size of cutter as far as possible through cutting out in the motion in the horizontal direction.

Preferably, the second film cutting assembly comprises a slide rail mounted on the base and a slide block capable of sliding on the slide rail, a roller which is in contact with a product and can roll relatively is mounted on the slide block, a film cutting knife fixed relatively to the roller is mounted on one side of the roller, and a spring capable of stretching in the vertical direction is mounted above the roller; when the surface of the product bent in the length direction is subjected to film pasting, the roller can be always pressed on the surface of the product by the spring.

Preferably, the first film cutting assembly comprises a heating wire for cutting a film, a film cutting cylinder for controlling the heating wire to move in the vertical direction, and a servo motor for controlling the heating wire to rotate in the horizontal direction, the heating wire is mounted at the output end of the film cutting cylinder, and the film cutting cylinder is mounted at the output end of the servo motor; cut out the membrane cylinder and drive the electrothermal wire downstream and fuse the pad pasting when quick downstream, servo motor can cut out the angle through the rotation control pad pasting of horizontal direction, because the product appearance of product is complicated, and two relative limits are not necessarily parallel, and the heating wire through servo motor control can be cut out the required pad pasting of product of various shapes.

Preferably, a first clamping jaw for clamping the film is arranged between the first film cutting assembly and the film pasting material roll during film cutting; the pad pasting is cliied to first clamping jaw can play the tensioning and cut the effect of department's pad pasting, when preventing first cutting the membrane subassembly downstream, takes out the pad pasting from the pad pasting material book to the effect is cut in the influence.

Preferably, the film drawing assembly comprises a second clamping jaw capable of moving in the horizontal direction, the second clamping jaw and the first clamping jaw are located at the same height, a certain distance is reserved between the first film cutting assembly and the first clamping jaw, and after the first film cutting assembly cuts, the second clamping jaw can clamp a section of the attached film left on the first clamping jaw, so that the attached film is drawn out of the attached film material roll.

Preferably, the number of pad pasting anchor clamps is two and more than two, and one of them pad pasting anchor clamps are installed on the robot, and other pad pasting anchor clamps are placed on the base, install on the pad pasting anchor clamps and can detect whether there is the sensor of pad pasting between first clamping jaw and the pad pasting material book, when the pad pasting in the pad pasting material book is used up, the sensor can't detect the pad pasting, continues the pad pasting with the pad pasting anchor clamps on the pad pasting anchor clamps replacement robot on the base this moment to the pad pasting anchor clamps change the material book for changing down, can't carry out the condition of pad pasting when having avoided changing the material book, has improved the efficiency of pad pasting.

The invention discloses a film pasting method of automatic film pasting equipment, which is carried out according to the following steps in sequence:
